you were on the official Devildom Ball with the brothers, an enormous party on diavolo's castle, Tho not only demons are allowed in, there was also Simeon and Luke, the exchange students from the angel school, and your fellow mage, Solomon, which is also an human like you

everyone was doing their own things, Lucifer was helping the little D's prepare the food table, and also preventing Beelzebub from eating the sweets before the party started, Mammon and Levi were arguing over the money Mammon owes levi, Satan and Belphie were talking with Mephistopheles, probably about how they hate Lucifer, Belphegor was sleeping, cause he doesn't know how to do anything besides that-

you were talking to Solo, Simeon and luke, suddenly, you hear Barbatos, diavolo's Butler, from behind you

"Sorry to interrupt, but, Lord diavolo wishes to speak with you" he starts, looking directly at you

what could diavolo want from you?

as you and Barbatos get closer to his office, you could hear an soft voice coming from his office, you couldn't help but get curious, and when you leaned in to hear, you heard Diavolo talking to himself

"calm down, Dia, just ask, you can do this..." you heard him say, and sigh softly

then, Barbatos knocked on the door

"Young master, can we enter?" he said, and then, you could hear Diavolo talk again, but he seemed nervous now

"Yeah! Come in..."

Barbatos opens the door, and motions you to enter, and as you do, you can see Diavolo on his desk, with what it seemed to be an small box in his lap, what was he planning?
